Introduction: Desert death is defined as any death that occurs in the desert and could be attributed to a list of causes including environmental, animal related, undetermined, and other causes. Death in the desert seems to be obscure and little discussed in the field of forensic medicine, despite its importance, and there is only limited literature available on this broad topic. This narrative review aims to identify the most common causes of desert death and its medicolegal implications. Desert death causes: Environmental causes of death could be a result of temperature and lightening-related causes. Moreover, a variety of animals found in deserts are considered to be threatening and fatal, in addition to other and undetermined causes. Medicolegal implications of desert death: Likely to arise from the difficulties faced in finding the cause of death are the identification of the victim and the postmortem injuries that occur. Conclusion: Desert death is a broad topic with great medicolegal significance. More information and case reports need to be added in the literature. Guidelines for people about the danger of going to deserts in specific weather conditions should be implemented. Safety regulations must be taken into account at all times.

Full textAbstract:
Recent decades have witnessed a surge in philosophical attention to the moral standing of non-human animals. Kantians, Neo-Kantians, utilitarians, and radical animal rights theorists have staked their claims in the literature. Here Fred Feldman’s desert-adjusted utilitarianism is introduced into the fray. After canvassing the prominent competitors in the dialectic, a conception of an overall moral ranking (relative to a moral choice scenario) consonant with desert-adjusted utilitarianism is developed. Then the conception’s implications regarding the particular locations of individual people and animals in such rankings across various scenarios is explored. Ultimately, it is argued that when it comes to evaluating whether or not some benefit (or burden) morally ought to be bestowed upon some specific person or animal, this new conception of an overall moral ranking is sensitive to a wider range of morally relevant phenomena than its more prominent competitors.

AbstractWhereas the reactions of animals to heat are largely behavioural, responses to water shortage are primarily physiological. These characters are exhibited in all terrestrial biomes, but are enhanced in the desert. Desert animals, in general, are either cryptically sand-coloured or else black when distasteful or poisonous. This applies to all three taxa under discussion; most beetles are black, most lizards cryptic. Scorpions, paradoxically, may be either black or cryptic. Examples of mimicry and protective resemblance are also cited. It is concluded that scorpions, beetles and lizards are especially successful desert animals, not so much on account of unique adaptations to the harsh and variable environment as to their innate qualities which have adapted them for life in hot, dry and unpredictable habitats.

The Mongolian–Transbaikalian region of the Central Asia is known for its wide range of intracontinental ecosystems from desert through steppe to taiga forest and mountain tundra. Data on the isotopic composition of carbon and nitrogen in the bone and dental tissues of herbivorous animals inhabiting the desert, steppe, and forest–steppe landscapes of Outer Mongolia and Western Transbaikalia are presented. The maximum values of the carbon isotope ratio are observed in animals from the desert (Gobi Desert) and the semi-desert landscapes, median (mean) δ13C is -17.9‰. The minimum values of δ13C were obtained by herbivorous animals of the forest-steppe and the forest landscapes (Transbaikalia), which median δ13C is -23‰. The fauna of the steppes (median δ13C is -21.7‰) has intermediate values of the carbon isotopic composition. According to the isotope composition of nitrogen, the isotope-geochemical isolation of ecosystems is less pronounced.

Full textAbstract:
Background Deserts are biologically rich habitats with a vast array of animals and plants adapted to xeric conditions, and most deserts are among the planet’s last remaining areas of total wilderness. Among North American deserts, the Chihuahuan Desert has the highest levels of diversity and endemism. To understand the effect of future climate change on plants distributed in this arid land and propose effective conservation planning, we focused on five endemic shrubby species that characterize the Chihuahuan Desert and used an integrative approach. Methods Ecological niche-based modeling, spatial genetics and ecological resistance analyses were carried out to identify the effect of global warming on the studied five shrubby species. Key areas that need to be preserved were identified taking into account the existing protected areas within the Chihuahuan Desert. Results The extent of future distribution will vary among these species, and on average expansion will occur in the western part of the Chihuahuan Desert. For most species low environmental resistance to gene flow was predicted, while higher future resistance was predicted for one species that would lead to increased population isolation. The highest haplotype diversity was identified in three hotspots. Based on future suitability of habitat and in the haplotype diversity we suggest preserving two hotspots of genetic diversity in the Sierra Madre Oriental, located in areas without protection. The third hotspot was detected in the well preserved Tehuacán-Cuicatlán Man and Biosphere Reserve. Conclusion Global climate change will have an effect in arid adapted plants, favoring expansion in the western of the Chihuahuan Desert however negatively affecting others with high ecological resistance disrupting gene flow. Two hotspots of genetic diversity in the Sierra Madre Oriental should be protected.

Africa has vast agricultural and other natural resources. Many of these resources have been exploited so that the resource is destroyed, rather than maintained in a sustainable way. With regard to agriculture and arable land, a particular problem is that of desertification, caused by spreading of desert areas into lands that have been damaged by over-grazing of animals,over-usage of water resources resulting in drought conditions, destruction of forest and tree coverage for cooking fuel, cropping of plants that cause soil erosion and depletion of soil minerals, and other undesirable abuses of land. Many thousands of hectares of previously arable land are lost to spreading deserts in all parts of Africa. The Sahel area, immediately south of the Sahara desert is the most affected area.

Full textAbstract:
In this paper we utilised a range of data sources to estimate the extent, density distribution and population size of the feral camel in Australia in 2008. Camels currently occupy 3.3 million km2 and are spread across much of arid Western Australia, South Australia, the Northern Territory and far western Queensland. Up to 50% of Australia’s rangelands are reported as having camels present. The research reported here supports a current minimum population estimate for the feral camel in Australia of ~1 million animals at an overall density of 0.29 camels/km2. Densities vary, and the modelling of available data indicates that two substantial areas of high density are present, one centred on the Simpson Desert and the other on the Great Sandy Desert. The high density area covering the eastern part of the Great Sandy Desert has predicted densities in the range of 0.5 to >2 animals/km2 whereas that on the Simpson Desert is in the range 0.5–1.0 animals/km2.

Full textAbstract:
Fresh water sustains human life and is vital for human health. For some of the poorest countries, 1 in 10 people do not have access to safe and easily accessible water sources. Water consumption by man continues to grow with an increasing population. The current supply of fresh water needs to be supplemented to meet future needs. Living nature provides many lessons for water harvesting. It has evolved species which can survive in the most arid regions of the world by passively collecting water from fog and condensation of water vapour in the night. Before the collected water evaporates, species have mechanisms to transport water for storage or consumption. These species possess unique chemistry and structures on or within the body for collection and transport of water. Among the high diversity of species surviving in deserts, only a handful of species have been studied. Based on lessons from nature, bioinspired water harvesters can be designed. In this paper, an overview of various desert plants and animals is given and known water harvesting mechanisms of some are presented. This article is part of the theme issue ‘Bioinspired materials and surfaces for green science and technology (part 3)’.

Full textAbstract:
AbstractIn 1996, approximately 70,000 mammal and lizard bones were recovered from Pintwater Cave in the northern Mojave Desert of southern Nevada. These bones date between 32,000 and 7350 14C yr B.P. Between 32,000 and 10,100 14C yr B.P. the local fauna consisted of a mix of xeric- and cool/mesic-adapted species. Ochotona princeps and Thomomys talpoides then occupied the region, although these animals were extirpated by the onset of the middle Holocene. Sauromalus obesus and Dipodomys deserti probably migrated to the region during the latest Pleistocene. Dipsosaurus dorsalis entered the Pintwater Cave record after 8000 14C yr B.P. Consistent with climatic interpretations for the northern Great Basin, these data suggest a cool and moist latest Pleistocene climate for the northern Mojave Desert. In contrast to the northern Great Basin, however, this region experienced predictable summer precipitation coupled with increasingly warmer winters by 10,100 14C yr B.P. In both regions, the warm middle Holocene began ca. 8300 14C yr B.P. However, whereas the northern Great Basin probably experienced warm and dry conditions at that time, the northern Mojave Desert remained warm with relatively predictable summer precipitation. The modern northern Mojave Desert biota probably was not established until after 8300 14C yr B.P.

Full textAbstract:
Many zoo facilities record weight data for their animals as part of their management protocols. However, there is a lack of evidentiary support in the literature on captive animal management for the use of this data as a health management tool and little discussion on the many ways in which keepers can interpret weight data. Often, animals' weights are considered in the context of their health only when other signs suggest health compromise. While aberrant weight values as secondary signs of illness are useful in confirming health compromise, it is possible that changes in weight can be observed as initial clues to illness. This study explores this possibility but acknowledges the need for an understanding of baseline weight values in order for comparisons to be possible. Furthermore, the study seeks to characterize the baseline weight data for a variety of captive Sonoran Desert animals, so that an individual weight value may be evaluated in the context of the norm for a particular animal species over a span of time. Specifically, animal care staff members at the Arizona-Sonora Desert Museum expect that weight data may express patterns of seasonality, due to the changes that animals undergo with time of year.

Full textAbstract:
Endothermic homeothermy is a major feature of the adaptive suites of tachymetabolic animals such as mammals and birds. The advantages homeothermy confers on birds and mammals include relative independence from the environment, a stable internal milieu, and possibly the ability to sustain high aerobic activity (Bennett and Ruben 1979). Some mammals in situations of limited water or energy availability, however, depart markedly from homeothermy and instead display patterns of heterothermy. Torpor is a lowering of body temperature (T(b)) to conserve energy and/or water. I studied the energetics of arousal from torpor in two desert pocket mice species. The species differed in warming rates and arousal durations, but used similar amounts of energy to arouse. The smaller species, Perognathus amplus, lost mass more quickly while fasting in the cold, yet waited as long as the larger species, Chaetodipus baileyi, before entering torpor. P. amplus maintained a lower T(b) during topor than C. baileyi. The thermodynamics of arousal indicated that metabolic rate during arousal was a function of T(b) but not ambient temperature (Tₐ), that the animals changed thermal conductance to increase heat gain when Tₐ was greater than T(b), and that Q₁₀ decreased during arousals. In contrast to torpor, adaptive hyperthermia provides desert mammals in dry, hot environments a means to conserve water that would normally be used for evaporative cooling. I modeled the effects of body size on adaptive hyperthermia and discovered that small mammals gain the most in terms of water savings using this strategy, and that small and large mammals can spend larger fractions of the day active than do medium size mammals. I demonstrated that two desert ground squirrel species make use of adaptive hyperthermia during the summer near Tucson, Arizona by following free-ranging squirrels implanted with temperature-sensitive radio transmitters. Ground squirrel T(b) fluctuated almost continuously, ranging from about 35°C to over 42°C, and rarely approached steady state. Of the two species studied, Ammospermophilus harrisii had higher mean T(b), similar maximum T(b), and lower T(b) variability compared to Spermophilus tereticaudus. These results are consistent with the more wide-ranging foraging style of A. harrisii compared to S. tereticaudus.

Full textAbstract:
Animals were given a preponderant position in Egyptian art, symbolism, and cultual practices. This thesis centres on the relationship between humans and animals during the predynastic period in Upper Egypt (Naqada I-IIIB, 4th millennium BCE), focusing on hippopotamus and crocodile as representatives of the Nile environment and antelope species as representatives of the desert environment. Depictions of these animals are analysed and compared with contemporary faunal remains derived from activities such as cult, funerary, or every day consumption. The material analysed covers several centuries: temporal evolutions and changes have been identified. The animals studied in this thesis were first used by the Naqada I-IIB elites as means to visually and practically express their power, which they envisioned in two contrasting and complementary ways. The responsibilities of the leaders were symbolised by the annihilation of negative wild forces primarily embodied by antelope species. In contrast, they symbolically appropriated positive wild forces, chief among them being the hippopotamus, from which they symbolically derived their power. Faunal remains from after mid-Naqada II are few, depictions of hippopotamus disappeared and those of crocodile became rare. Antelope species became preponderant, especially on D-ware vessels, which were accessible to non-elite people. However, toward the end of the predynastic period, antelope species came to be depicted almost exclusively on high elite material; they lost their individuality and became generic representatives of chaotic forces that the leaders and early rulers had to annihilate in order to maintain control and order.

Full textAbstract:
I studied diel activity patterns of female desert bighorn sheep ( Ovis canadensis mexicana) in the Little Harquahala Mountains, Arizona, July 1985-June 1986. Diurnal activity patterns were similar throughout the year. Nocturnal activity patterns were similar for all seasons except spring when activity significantly (P = 0.003) decreased. Bighorn sheep were active an average of 39 and 33% of any given hour during the day and night, respectively. Diurnal ambient temperatures and relative humidity were significantly (P ≤ 0.048) correlated with bighorn sheep activity during all seasons. Bighorn sheep spent a majority of the time foraging in the fall and winter, but spent more time resting during spring and summer. Bighorn sheep obtain water in their food throughout the day; percent moisture content of forage species remained high (≥ 32%) for any given hour of the day throughout the year.

Full textAbstract:
The number of desert bighorn sheep (Ovis canadensis mexicana) in Pusch Ridge Wilderness (PRW), Santa Catalina Mountains, Arizona has declined to between 50 and 100 animals. Sheep have restricted movements to the southwest corner of PRW. I developed a model based on nitrogen (N) content of forage and forage quantity to measure seasonal changes in nutritional carrying capacity of sheep use areas in PRW. Forage based estimates of animals numbers were greater for April to September than for October to March. My study suggests that forage is not limiting desert bighorn sheep in PRW and illustrates the potential to support more desert bighorn sheep in PRW than the current population. Seasonal fluctuations in range productivity should be examined in relation to human disturbances proximal to desert bighorn sheep habitat and fire management programs for PRW.

Full textAbstract:
Variability is a universal, but poorly understood, property of ecosystems. A common belief that environmental variability has a destabilizing effect on species coexistence is being challenged by a growing body of theoretical research; variance in resource abundances may actually promote species coexistence. Here, I develop three models which give ecological conditions for coexistence on a single resource. The first considers a resource whose abundance varies seasonally. Coexistence may be possible if there is a tradeoff between foraging efficiency and maintenance efficiency. The first species can forage profitably on low resource abundances while the second uses dormancy to "travel" inexpensively between temporal periods of high resource abundance. The second considers a resource whose abundance varies spatially. Coexistence may be possible if there is a tradeoff between foraging efficiency and the cost of travel. The first species forages patches to a lower giving up density while the second can inexpensively travel between patches with high resource abundances. The third considers an environment in which foraging costs change seasonally. Coexistence may be possible if there is a tradeoff between the cost of foraging during different seasons. The species which is the most efficient forager changes seasonally. Because coexisting species often exhibit little apparent diet or habitat separation, seed-eating desert rodents offer a promising community for testing the three aforementioned mechanisms of coexistence. In a community of four granivorous rodents, (Perognathus amplus, Dipodomys merriami, Spermophilus tereticaudus, and Ammospermophilus harrisii), I used artificial seed patches to measure species and habitat specific foraging efficiencies. The third mechanism of coexistence appears to explain the presence of P. amplus, D. merriami, and S. tereticaudus in the community. Each enjoys a season during which it is the most efficient forager. The second mechanism of coexistence explains the presence of A. harrisii in the community. This species preferred to forage a large number of widely spaced patches to a high giving up density rather than foraging a few patches to a low giving up density.

The distribution of desert species of plants and animals in the Ulyanovsk region (Middle Volga region) is associated with two main reasons: native origin and penetration (entry) from arid and semiarid regions. Deserted species of indigenous origin, as a rule, are located on the northern border of the range and move north along similar biotopes - salt marshes, saline steppe areas, arid steppes with elements of semi-deserts, etc. Most of these species are rare and are listed in the regional Red Book. Intertile desert species are often occupied by ruderal biotopes - silver goof, tamarix, etc. In general, in the biota of the Ulyanovsk region, desert species account for about 5%.

Due to the climate change happening on the earth, the immunity of both humans and animals is decreasing along with this the plants are also getting affected. The main reason for which is the continuous increase in the temperature of the earth. The main reason for the increase in temperature is anthropogenic action, due to which carbon dioxide is emitted in high quantity in the atmosphere and this generates greenhouse effect. Due to the excessive emission of carbon dioxide, frequent changes in the climate are happening very fast and their ill effects are clearly visible. Due to this, the frequency of natural disasters is also increasing and their area is also increasing, due to which the biodiversity is also being lost. Because only natural plants have the amazing ability to prevent negative changes in the climate and adjust by absorbing carbon dioxide emitted in large quantities. In this sequence, there is an urgent need to implement the possibilities of reducing carbon dioxide emissions by cultivating carbon farming from the dry shrub Kheemp (Lepatadenia pyrotechnica), which is found abundantly in the Thar Desert.

Full textAbstract:
The Arabic poem remained on a unified approach for long periods, and its mold was set by a group of paternal poets who were classified in the first class among critics, and Imru’ al-Qais, Zuhair, and al-Nabigha al-Dhubiani came in the forefront. With these ancestors, the Arabic poem became a model to be followed by those who came after them, and they even began to adhere to the same approach as a custom that should be followed. So the poem had to start by standing on the ruins, and then move on to depicting the different factors that arouse the poet’s approval. Finally, he ends with the main theme of his poem, whatever its purpose. But the oath that sparked great controversy later and voices rose among poets to leave it and depart from it is the beginning of the poem, or what is known as "standing on the ruins." In fact, the phenomenon of the introduction to the poem arose related to the environment and the type of civilization in it, and it remained connected to it and developed with it. These introductions were not an artistic tradition devoid of feelings and ideas, but rather constituted a methodology that carried the poets' emotions, their memories, and the events that passed through them. The development in the forms of these introductions, or the invention of other new forms, is due to the development of environmental factors and social life. Which requires modifying these introductions to keep pace with the new intellectual contents in their stylistics. In the past, the poem was a description of the ruins and the animals, a description of the horse, the camel, the arduous journey, and the description of the desert with its fears. As for the poets of the following eras, they changed - even if it was a little - in the readings of their poems, and most of their poems were not standing on ruins and describing the lost. On the contrary, a description of amusement, promiscuity, leisure life, and wine appeared in the Abbasid poetry, because they lived in a new environment. The son of Baghdad could not describe the arduous journey, the desert, and the animals that he did not see, because he was the son of a new environment, and every person starts from his environment.

Full textAbstract:
Introdução: Os animais silvestres vêm sofrendo por terem que deixar de viver em seu habitat natural por contas das ações antrópicas. Isso acontece tanto devido ao desmatamento quanto pelo tráfico destes animais, sendo que os números de ambos que vem crescendo nos últimos anos. Em contrapartida, a quantidade de fotos e vídeos de animais selvagens nas redes sociais também vêm crescendo. Da mesma forma que a venda de peixes explodiu após o lançamento das animações “Procurando Nemo” e “Procurando Dory”, o tráfico de animais têm aumentado em proporções semelhantes à exposição desses nas redes sociais. Objetivo: Com isso, o objetivo deste trabalho é analisar a influência das redes sociais na educação ambiental, no que diz respeito a antropomorfização dos animais silvestres. Metodologia: Para isso, será feita uma revisão bibliográfica e documental sobre o tema. Resultados: Foi possível verificar que as redes sociais têm influenciado diretamente na educação como um todo. Além do trânsito de informação direta, as informações indiretas geram conclusões muitas vezes equivocadas. Nesse sentido, a exposição de animais silvestres sendo tratados como animais silvestres, ou até como humanos proporciona o desejo de obtê-lo, juntamente com a ideia de que não existe problema nisso. Conclusões: Então, é possível concluir que a tais ações geram desinformações e prejuízo ao bem-estar animal e ambiental. Portanto, é necessário ações em conjunto entre as redes sociais, as políticas públicas e das escolas para combater o tráfico, inibir a exposição de animais silvestres antropomorfizados e educar sobre a importância da permanência destes no seu habitat natural.

Full textAbstract:
Hemodynamics have been linked to the genesis and progress of vascular disease in humans and animals1. Disturbed flow patterns such as stagnant flow or flow reversal lead to low or oscillating wall shear stress (WSS). Several in-vivo studies have correlated these types of WSS with disease formation1, 2. The desire to find correlations between markers of vascular disease and mechanical stimuli and because of their easier availability has led to an increasing number of animal model studies. The mouse, in particular, is a commonly used animal for investigating vascular disease formation and progression. Suo et al., were one of the first to relate findings on the molecular level with WSS1. They found increased VCAM and ICAM expression in areas of low WSS. More recently Hoi et al.2, have shown a correlation between atherosclerotic plaque development and hemodynamic parameters such as low time averaged wall shear stress (TAWSS) and Oscillatory Shear Index (OSI).

Full textAbstract:
In our work we have formulated the general objective to develop affective communication in the children with Down syndrome by presenting educational software that motivate the desire to communicate and interrelate with others which can be a trigger vector to stimulate speech and expression of attitude towards the surrounding world. Therefore, we formulated two hypotheses: 1. Considering the love of the children with Down syndrome for animals and their ability to imitate others, we assumed that educational software facilitate children's desire to interact through nonverbal communication and through an expression of a state of mind based on simple verbal structures dominated by prosodic elements; 2 We assume that learning affective communication generates a progress in the direction of understanding the world around them and becomes a catalyst factor for their desire to learn. In order to decipher these purposes we conducted a research on a group of 30 children with Down syndrome aged between 8 and 10 years. We used in the therapy program, through the educational software, several activities involving different animals in different situations and several children who expressed a positive attitude towards them using petting, touch, gesture, intonation and verbal exclamation, short words which expressed appreciation and the animals responded using characteristic sounds and "words" of thanks. In the next step we followed subjects undergoing investigation in real situations in order to verify that those things acquired through educational software extend to everyday circumstances. After applying the above tests we found out that the two hypotheses were tested, this fact meaning that the educational software have contributed to shaping the affective communication and to performing a significant leap in diversifying their attitudinal expression towards the surroundings. We discovered that there was an increased desire to have contact with others and to express preferences using more verbal expressions similar to human characteristics.

Full textAbstract:
Scattered throughout the Great Basin and the drainages of the upper Colorado and Rio Grande Rivers is a legacy of prehistoric and historic (i.e., post-Spanish contact) Indian rock art that represents a several-thousand year old tradition of creating culturally meaningful images on stone. Depending on the nature of the stone surface, and also on the intent of the "artist", the images were either pecked, scratched or abraded into the stone, or painted on suitably smooth and protected cliff walls. The terms petroglyph and pictograph are respectively applied to these two basic techniques. Petroglyphs typically were pecked through the dark patina coating, which slowly develops on many rock surfaces in the desert environment, to disclose the lighter colored rock beneath, whereas mineral-based pigments were employed in making pictographs. Among the inventory of images are human-like (anthropomorphic) and animal (zoomorphic) forms, as well as a large variety of abstract elements and more esoteric designs that are subject to various interpretations. With time, the rock art of the Great Basin area generally evolved from the abstract to the more representational, although many abstract designs remained popular (i.e., meaningful) throughout the area's long history.

Full textAbstract:
A Medicina Veterinária tem passado por uma grande revolução em busca do bem-estar animal. Um problema muito incômodo para o cão e seu tutor é a perda da visão. Normalmente os proprietários notam alterações no aspecto dos olhos de seu animal ou alterações em seu comportamento (colisão com objetos, relutância em subir ou descer escadas, apatia, agressividade, etc). A cegueira ataca animais de diversas idades, raças e portes, podendo ser gradual ou súbita. Das causas de cegueira em cães, as mais comuns são: catarata; alterações de retina; glaucoma; luxação de lente; e uveíte. Quando essa cegueira é aguda, o animal tende a apresentar maior dificuldade de adaptação. Esta dificuldade proporciona uma maior tendência para acidentes causados por colisões em objetos ou obstáculos, podendo trazer consequências na saúde do cachorro, como lesões no corpo (principalmente na região da cabeça), lesões oculares e até problemas neurológicos. O objetivo deste trabalho é relatar as formas de manejo do cão com cegueira aguda, a fim de proporcionar uma melhor adaptação, evitar acidentes e melhorar a qualidade de vida dos animais cegos. Foi realizada uma revisão bibliográfica de literatura utilizando os termos: “cegueira”, “cães”, “cegos” e “aguda” nos idiomas inglês e português. Foram pesquisados nas bases de dados do Google Acadêmico. Em grande parte dos casos os cães tendem a se adaptar à cegueira; os sentidos do olfato e da audição auxiliam na sua localização. Porém, é necessário um período de adaptação e alguns recursos podem auxiliá-los em suas atividades diárias. É possível, com pequenas adaptações no estilo de vida e na rotina, ajudar a manter o cão seguro e confiante. Entre eles: evitar objetos deixados no caminho do cachorro e deixar as passagens desobstruídas; cuidar com estruturas pontiagudas na altura do animal; não alterar a disposição dos móveis; manter comedouros e bebedouros sempre nos mesmos locais; estimular os sentidos auditivo e olfativo; além de manter uma rotina de acompanhamento com o médico veterinário. Uma maneira de garantir maior autonomia e segurança para o cão cego é adquirir uma solução própria para ele. Existem várias opções no mercado, como viseiras que protegem os olhos, bambolê de proteção e coleira vibratória. Estas ferramentas evitam colisões intensas entre o cachorro e o obstáculo. O bambolê de proteção para cães cegos é um aro acoplado no corpo do cachorro fazendo com que a colisão nos objetos ocorra diretamente no acessório e não no cão. A coleira vibratória consiste em um acessório que detecta os obstáculos que estão à frente e emite alertas vibratórios, os quais se intensificam à medida que os obstáculos estiverem mais próximos. A mudança de visão da população moderna traz os animais como integrantes da família. Assim, a preocupação com o bem-estar dos cães aumenta e a busca por soluções para seus problemas se faz cada vez mais importante. Com o presente resumo, constatou-se que, com os devidos cuidados, é possível manter a saúde e a qualidade de vida do cão cego. Resumo sem apresentação oral.

Full textAbstract:
Once upon a time, there was a place with good soil for plants and good sources of water for wild animals. Many, many plants grew there, and many wild animals made it their home. People liked it too. In fact, so many people wanted it to be their home, they built a city. The world's big cities -that are now full of skyscrapers and wide concrete avenues, and where the only wild animals live in zoos- once looked very different. Many were farms. A few were jungles or swamps. A handful were desert oases. Even today, cities cannot be separated from the natural environment. Natural ecosystems provide the resources that cities need to develop and grow, including water, clean air, soil, food, and energy.

Full textAbstract:
Control of agro-associated pathogens is becoming increasingly difficult due to increased resistance and mounting restrictions on chemical pesticides and antibiotics. Likewise, in veterinary and human environments, there is increasing resistance of pathogens to currently available antibiotics requiring discovery of novel antibiotic compounds. These drawbacks necessitate discovery and application of microorganisms that can be used as biocontrol agents (BCAs) and the isolation of novel biologically-active compounds. This highly-synergistic one year project implemented an innovative pipeline aimed at detecting BCAs and associated biologically-active compounds, which included: (A) isolation of multidrug-resistant desert soil bacteria and root-associated bacteria from medicinal plants; (B) invitro screening of bacterial isolates against known plant, animal and human pathogens; (C) nextgeneration sequencing of isolates that displayed antagonistic activity against at least one of the model pathogens and (D) in-planta screening of promising BCAs in a model bean-Sclerotiumrolfsii system. The BCA genome data were examined for presence of: i) secondary metabolite encoding genes potentially linked to the anti-pathogenic activity of the isolates; and ii) rhizosphere competence-associated genes, associated with the capacity of microorganisms to successfully inhabit plant roots, and a prerequisite for the success of a soil amended BCA. Altogether, 56 phylogenetically-diverse isolates with bioactivity against bacterial, oomycete and fungal plant pathogens were identified. These strains were sent to Auburn University where bioassays against a panel of animal and human pathogens (including multi-drug resistant pathogenic strains such as A. baumannii 3806) were conducted. Nineteen isolates that showed substantial antagonistic activity against at least one of the screened pathogens were sequenced, assembled and subjected to bioinformatics analyses aimed at identifying secondary metabolite-encoding and rhizosphere competence-associated genes. The genome size of the bacteria ranged from 3.77 to 9.85 Mbp. All of the genomes were characterized by a plethora of secondary metabolite encoding genes including non-ribosomal peptide synthase, polyketidesynthases, lantipeptides, bacteriocins, terpenes and siderophores. While some of these genes were highly similar to documented genes, many were unique and therefore may encode for novel antagonistic compounds. Comparative genomic analysis of root-associated isolates with similar strains not isolated from root environments revealed genes encoding for several rhizospherecompetence- associated traits including urea utilization, chitin degradation, plant cell polymerdegradation, biofilm formation, mechanisms for iron, phosphorus and sulfur acquisition and antibiotic resistance. Our labs are currently writing a continuation of this feasibility study that proposes a unique pipeline for the detection of BCAs and biopesticides that can be used against phytopathogens. It will combine i) metabolomic screening of strains from our collection that contain unique secondary metabolite-encoding genes, in order to isolate novel antimicrobial compounds; ii) model plant-based experiments to assess the antagonistic capacities of selected BCAs toward selected phytopathogens; and iii) an innovative next-generation-sequencing based method to monitor the relative abundance and distribution of selected BCAs in field experiments in order to assess their persistence in natural agro-environments. We believe that this integrated approach will enable development of novel strains and compounds that can be used in large-scale operations.

Full textAbstract:
Robert Duncan Milne (1844-99), from Cupar, Fife, was a pioneering author of science fiction stories, most of which appeared in San Francisco’s Argonaut magazine in the 1880s and ’90s. SF historian Sam Moskowitz credits Milne with being the first full-time SF writer, and his contribution to the genre is arguably greater than anyone else including Stevenson and Conan Doyle, yet it has all but disappeared into oblivion. Milne was fascinated by science. He drew on the work of Scottish physicists and inventors such as James Clark Maxwell and Alexander Graham Bell into the possibilities of electromagnetic forces and new communications media to overcome distances in space and time. Milne wrote about visual time-travelling long before H.G. Wells. He foresaw virtual ‘tele-presencing’, remote surveillance, mobile phones and worldwide satellite communications – not to mention climate change, scientific terrorism and drone warfare, cryogenics and molecular reengineering. Milne also wrote on alien life forms, artificial immortality, identity theft and personality exchange, lost worlds and the rediscovery of extinct species. ‘A New Palingenesis’, originally published in The Argonaut on July 7th 1883, and adapted in this comic, is a secular version of the resurrection myth. Mary Shelley was the first scientiser of the occult to rework the supernatural idea of reanimating the dead through the mysterious powers of electricity in Frankenstein (1818). In Milne’s story, in which Doctor S- dissolves his terminally ill wife’s body in order to bring her back to life in restored health, is a striking, further modernisation of Frankenstein, to reflect late-nineteenth century interest in electromagnetic science and spiritualism. In particular, it is a retelling of Shelley’s narrative strand about Frankenstein’s aborted attempt to shape a female mate for his creature, but also his misogynistic ambition to bypass the sexual principle in reproducing life altogether. By doing so, Milne interfused Shelley’s updating of the Promethean myth with others. ‘A New Palingenesis’ is also a version of Pygmalion and his male-ordered, wish-fulfilling desire to animate his idealised female sculpture, Galatea from Ovid’s Metamorphoses, perhaps giving a positive twist to Orpheus’s attempt to bring his corpse-bride Eurydice back from the underworld as well? With its basis in spiritualist ideas about the soul as a kind of electrical intelligence, detachable from the body but a material entity nonetheless, Doctor S- treats his wife as an ‘intelligent battery’. He is thus able to preserve her personality after death and renew her body simultaneously because that captured electrical intelligence also carries a DNA-like code for rebuilding the individual organism itself from its chemical constituents. The descriptions of the experiment and the body’s gradual re-materialisation are among Milne’s most visually impressive, anticipating the X-raylike anatomisation and reversal of Griffin’s disappearance process in Wells’s The Invisible Man (1897). In the context of the 1880s, it must have been a compelling scientisation of the paranormal, combining highly technical descriptions of the Doctor’s system of electrically linked glass coffins with ghostly imagery. It is both dramatic and highly visual, even cinematic in its descriptions, and is here brought to life in the form of a comic.

Exploring methods of measuring and collecting data relating to imported food production standards. Food Standards Agency, June 2023. http://dx.doi.org/10.46756/sci.fsa.ard467.
Full textAbstract:
As global trade markets have expanded, there has been an increasing volume of agricultural commodities and food products imported to, and exported from, the United Kingdom (UK). In response to these market and political changes, standards for imported foods are being implemented to control the trade of goods and services. Alongside the development and implementation of standards for imported foods, there has been a growing public desire to understand where the food we eat comes from, and increasingly, to understand not just the safety of food, but the inter-country variation in the sustainability of food production practices. For example, is a product sourced from one country comparable to another country in terms of animal welfare, environmental sustainability (for example, greenhouse gas emissions, deforestation, biodiversity etc.) and nutritional composition. To inform future research needs, the Food Standards Agency required a detailed understanding of the current data and literature landscape regarding imported food standards, with a particular focus on data availability around three themes: animal welfare, environmental sustainability, and nutritional composition. Data on food safety was not considered as part of the review as this has been well documented in previous research by the Food Standards Agency. To achieve the research needs, a review was undertaken to explore and assess measurable metrics, which could be used to measure and monitor the consistency or differences of imported food production standards across the three themes. The assessment of each theme was coupled with parameters relevant to imported food products consumed in the UK. In addition, the research aimed to inform data gaps and requirements. The information outlined in this report provides an independent assessment of how the three themes are currently considered within international imported food standards and trade agreements. The outputs will inform the Food Standard Agency’s 2023 Annual Review of Food Standards across the UK.
